Here’s a helpful video tutorial contribution from Adafruit community member David Nash. Thanks for sending this in!

This is a simple project that builds on several of your Raspberry Pi Lesson projects that I thought you might consider including in a more advanced lesson. All of the components were purchased from Adafruit. The project uses your 8×8 matrix as the display so, when the Python program is automatically invoked from bootup, it requires no monitor or keyboard to run. It uses 12C for input and output to two devices and uses one GPIO analog interface. It’s a neat project for a number of reasons not least of which is it provides a means of verifying that your programmable home thermostat is functioning properly.
